Samples of vegetation were taken using a small net (mesh width 70 µm) or cut off and washed in sampled water, as well as collecting water from the sample site. The collected vegetation and material were kept in glass bottles. Water from the samples was extracted into a Petri dish and then examined using a dissecting microscope. Each worm that was found was picked up with a glass pipette and put on a slide. Before they were preserved, the collected worms were first studied alive using a dissecting and a light microscope. Slightly squeezed specimens were drawn freehand and photographed using a digital camera attached to a Zeiss Axio Imager M
